LONDON, September 12 — Britain sold £4.25 billion (about US$5.4 billion) of 30-year government bonds at a yield of 5.82%, the highest recorded since records began in 1998, and the number has set off a round of urgent arithmetic in the UK savings market. The mechanics here are simple enough. When gilt yields climb, the income available on newly issued government debt climbs with them.
Cash sitting in a high street instant access account does not follow. Anna Macdonald, investment strategy director at Hargreaves Lansdown, put the gap in concrete terms: £20,000 (about US$25,400) in an average instant access account was earning around £190 (about US$241), when it could potentially earn as much as £764 (about US$970).
But Macdonald’s own advice cuts against the alarmism that tends to accompany a headline yield. Speaking to Sky Money, she cautioned that investors should “avoid making knee-jerk decisions” in response to market movements. “While rising yields can create short-term volatility, they have also improved the income available from cash, bonds and other lower-risk assets,” she said.
The catch in buying gilts directly
For retail investors willing to buy gilts directly and hold them to maturity, the appeal is twofold: a locked-in higher yield, and an exemption from capital gains tax on the gains. Macdonald suggested a further refinement — purchasing low-coupon bonds and holding them until maturity, so that a greater proportion of the return arrives as a capital gain, maximising the CGT exemption. On closer reading, though, that strategy carries its own risk.
Low-coupon bonds are more susceptible to price volatility. If you need to sell before maturity, you are exposed to whatever the market is paying that day.
The tax advantage only holds if you can wait. “Diversification remains important, and investors should make sure their portfolio matches their long-term goals and attitude to risk,” Macdonald said.
Why the cash is stuck
The warning lands against a broader problem in UK savings. The Office for National Statistics confirmed that Consumer Prices Index inflation rose to 2.9% in July, up from a 15-month low of 2.6% in June. That followed a 13% increase in Ofgem’s energy price cap last month, which pushed the average gas and electricity bill up by £221 (about US$280) to £1,862 (about US$2,360) per year.
New analysis of CACI data by the savings app Spring found that £502 billion (about US$637 billion) is sitting in adult savings accounts earning 2.5% or less — below the 2.9% inflation rate, meaning those funds are losing ground in real terms. The typical account earning below that threshold holds a balance of £8,099 (about US$10,280).
Harriet Guevara, chief savings officer at Nottingham Building Society, framed it as a question of matching accounts to purpose. “This is a reminder that inflation still matters. Even small increases can erode the spending power of cash over time, so it is worth checking that savings are held in an account paying a competitive rate and that the account still matches the level of access needed,” she said.
“Splitting savings across different goals can help balance flexibility and certainty. Easy-access accounts may suit an emergency fund or short-term plans, while fixed-rate accounts can provide more reassurance for money you will not need straight away — and are particularly competitive at the moment for those able to lock money away.” What to watch next is whether the gilt yield holds at these levels or retreats, and whether high street banks respond by repricing their instant access rates.
Until they do, the gap between what savers earn and what the bond market pays stays open.
